Gravity and Inertia

Front

What is inertia?

Back

Inertia is the tendency of an object to resist a change in its motion. It means that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by a force.

Front

What does mass refer to?

Back

Mass is the amount of matter in an object. It does not change regardless of the gravitational field.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other. It is what keeps us on the ground and causes objects to fall.

Front

How does gravity affect objects in the Solar System?

Back

Gravity is the force that keeps planets in orbit around the sun and moons in orbit around planets.

Front

What is the relationship between force and inertia?

Back

To change the motion of an object, inertia must be overcome by a force acting on the object.

Front

What happens to a resting object due to inertia?

Back

A resting object will remain at rest due to inertia.

Front

What is the difference between weight and mass?

Back

Weight is the force of gravity acting on an object, while mass is the amount of matter in the object. Weight can change with gravity, but mass remains constant.

Front

Can mass change in different gravitational fields?

Back

No, mass does not change in different gravitational fields.

Front

What is an example of inertia in everyday life?

Back

When a car suddenly stops, passengers lurch forward due to inertia.

Front

What is the effect of gravity on falling objects?

Back

Gravity causes all objects to fall towards the Earth at the same rate, regardless of their mass.
